==Geothermal plant==
Unterhaching began construction on a [[geothermal power]] plant called Geothermie Unterhaching in 2004. The plant was the first industrial-scaled project in Germany to use the [[Kalina cycle]].<ref>{{Cite web|last=GeoEnergy|first=Think|date=2013-12-18|title=Geothermal Gruenwald buys stake in Geothermal Unterhaching {{!}} ThinkGeoEnergy - Geothermal Energy News|url=https://www.thinkgeoenergy.com/geothermal-gruenwald-buys-stake-in-geothermal-unterhaching/|access-date=2021-09-11|language=en-US}}</ref><ref name=":0">{{Cite web|last=GeoEnergy|first=Think|date=2018-07-23|title=Equipment of Kalina geothermal power plant of Unterhaching to be sold {{!}} ThinkGeoEnergy - Geothermal Energy News|url=https://www.thinkgeoenergy.com/equipment-of-kalina-geothermal-power-plant-of-unterhaching-to-be-sold/|access-date=2021-09-11|language=en-US}}</ref>  The drilling works lasted about six month for each of the two boreholes. While the first drill hole was finished in fall 2004, the second was completed in winter 2007. The plant became operational in the winter of 2007/2008.<ref>{{cite web | url=https://geothermie-unterhaching.de/cms/geothermie/web.nsf/id/li_fernwaerme.html | title=Fernwärmenetz wächst weiter - GEOTHERMIE Unterhaching GMBH & Co KG }}</ref><ref>{{cite web | url=https://www.geothermie-unterhaching.de/cms/geothermie/web.nsf/id/pa_daten_fakten.html | title=DATEN & FAKTEN - GEOTHERMIE Unterhaching GMBH & Co KG }}</ref> The plant was shut down in 2017, as temperature fluctuations meant it could only generate power effectively in the summer.<ref name=":0" />
